My 2012 W204 C63 Saloon is without doubt the best car I have ever owned, the noise, the drama.,...it forever puts a smile on my face. I bought it in July 2020 and it currently has 64k miles on the clock in which I have covered almost 4k of them. Soon after I bought it, I noticed that the gear changes at lower speeds were a tad lumpy. The car pulling away at medium throttle feels a little rough and this is more noticeable when the car is upto temperature. Floor the car and push it hard and that roughness goes and it pulls like a train through the gears. In September 2020 it went into Mercedes Warrington and had £2500's worth of work carried out fixing various oiul leaks from under the engine and it had an ATF change. No more leaks and the engine is as clean as a whistle. The car doesnt use any oil or water and no funny noises at all on start up....
In December 2020, I was still unhappy with the 'jerkiness' of the gearbox at lower speeds and the roughness of it especially when warm. It went back into Mercedes and it had the gearbox recalibrated (whatever that means). I thought this had solved it as the car felt much much nicer to drive and smoother. However, in the past week or so the jerkiness and lumpiness of the gear changes has come back again.
In addition to this, when pulling away at junctions or on a slight incline with the wheels turned, its making a rumbling/scraping noise from the rear. Im thinking that maybe brake related (something catching) or could it be the diff? Is this linked to the lumpiness and slight jerkiness at lower speeds? Is it the gearbox at fault? All such questions running around my mind and to be honest its spoiling the experience for me at present. I know these cars are going up in value. Mine is very very clean with Full Mercedes History and I know it would fetch circa £21k if I was to put her up for sale. However, webuyanycar.com have offered £18500.....i know they will knock me down but part of me is like if I get £18k I would probably sell and use the money to get something else....
If only I could find somebody to diagnose the problem for me. Its been on the ramps in two seperate garages and neither could find any issues with it underneath. What you guys do in my opinion? Get shut or spend spend spend on getting an Indy to try and find out what is what?
